Quantum Noise and Entanglement Entropy

Abstract:
Entanglement entropy is a measure of quantum many body correlations between the parts of a many body system. It has emerged as a useful quantity in broad areas of theoretical physics, from cosmology to condensed matter and quantum information. In the first part of the talk I will describe universal relations between entanglement entropy and statistics of current flowing through a quantum point contact, allowing to test seminal results of conformal field theory such as the prediction of Holzhey, Larsen and Wilczek for entanglement entropy of fermions. In the second part I will concentrate on new results on radiation matter entanglement in dielectrics and conductors and its properties.
